Title: Air cleaning device
Inventor: KATAOKA MASAYUKI
IPC: B01D53/86
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To sufficiently perform sterilization and deodorization as required in accordance with the absence or the presence of human body by possessing an ozonizer, a sterilization and deodorization means of an ozone decomposition catalytic device and a blowing means and providing a member for opening and closing a flow passage in the flow passage in the ozone decomposition catalytic device. SOLUTION: In the case that human body is present in a room, the sterilization and deodorization is performed by introducing an air in the room into an air cleaning device, shifting a switching damper 7 to a position of a dotted line and decomposing ozone generated in the ozonizer 6 in the ozone decomposition catalytic device 8. The sterilized and deodorized air is supplied to the room after the remaining ozone in the air is naturally decomposed by the strong pressure strong blowing of a fan 11 to make harmless and odorless. On the other hand in the case that human body is absent in the room, the switching damper 7 is shifted to a continuous line, the ozonizer is operated and only the ozone-containing air is introduced into the room. After that, the operation of the fan 11 is started and the switching damper 7 is shifted to the position of the dotted line.  As a result, the air in the room is circulated and ozone is decomposed by the action of the ozone decomposition catalytic device 8.

Abstract: PURPOSE:To eliminate waste of engine drive force by providing a clutch main body having electroviscous fluid capable of changing a transmission quantity of drive force between a drive member and a driven member and a control device for controlling voltage applied to the electroviscous fluid. CONSTITUTION:A quantity of voltage applied to electroviscous fluid is controlled so as to transmit drive force required for an oil pump 3a between a case 2 and an outer plate 11 of a clutch main body 1 and an output shaft 3 and an inner plate 12. Accordingly, viscosity of the electroviscous fluid is changed so that this fluid may transmit drive force of a quantity required for the oil pump 3a between a case 2 side and an output shaft 3 side, while the drive force exceeding the required quantity is not transmitted to the oil pump 3a by means of slipping between the case 2 side and the output shaft 3 side. Consequently, only necessary drive force is transmitted all the time to drive the oil pump 3a irrespective of an engine speed.

CONSTITUTION:Based on a size signal from a recording paper size detecting circuit 141, a CPU 142 judges a region 150 on a photosensitive belt 2 which region corresponds to a recording paper, and simultaneously, determines the position of a writing head 5 based on an image information width signal from an information width generating circuit 146. As a result, a pulse motor 144 is driven through a driving circuit 143, and the head 5 fixed to a belt 131 is moved to a position corresponding to the first writing region 151 by rotating a driving roll 132. Thereafter, controlling electrodes in the head 5 are turned ON and OFF according to image information, thereby form an electrostatic charge image in the writing region. Next, the head 5 is moved from the first electrostatic charge image forming region 151A to the next writing region 152. Since the writing head small in length is used as a printer, versatility can be enhanced while preventing the cost from being raised.

IPC: B29C43/36
Filed: 1984-12-08
Abstract: PURPOSE:To prevent a skin from wrinkling, breaking and the like and a laminated body from deforming such as twisting and the like by a method wherein molding is performed by supplying resin from the required molten resin passage between the skin material and a female mold or a male mold after the cutting-off of the skin and before the completion of the mold closing. CONSTITUTION:A skin material 10 is arranged between a female mold and a skin material fixing frame 4, which is shiftably mounted on the male mold side or female mold side of a mold assembly 1 having a male mold 2 and a female mold 3 and at the same time has a sliding surface for the whole periphery of the outer side surface 8 of the male mold 2 to slide, and cut off by shifting of either the female mold 3 or the skin material fixing frame 4. After the peripheral edge of the skin 10 is pinched between the fimale mold 3 and the frame 4, the skin 10 is pinched between the female mold 3 and the frame 4, the skin 10 is shaped by closing the female mold 3 and the male mold 2. Molding is performed by supplying molten resin 11 between the skin 10 and the female mold 3 or the male mold 2 after the cutting-off of the skin and before the completion of the mold closing. Consequently, because the process is simple, the manufacture mentioned above is suitable for mass-production and neither wrinkles nor breaches generate in the skin 10. At the same time, because the residual stress due to orientation and the like is little, the laminated body 14 with little deformation such as twisting and the like is obtained.
